Scientists from Nagoya University of Technology in Japan have proposed a new way to create carbon nanobulbs (CNOs), which are nano-sized carbon structures formed by nested carbon spheres. It was proposed to be produced taking into account fish scales.

Collagen is the main ingredient required for nano-bulbs produced from flakes. It can absorb the necessary amount of microwave radiation to rapidly increase the temperature, which when heated leads to thermal decomposition, which promotes CNO synthesis.

Thanks to the excellent electrical and thermal conductivity of nanobulbs, they are used in biomedicine, bioimaging – a visualization method for real-time observation of processes occurring in the body. Nano bulbs are also used in the manufacture of panels for TVs and other electronic devices.

The approach proposed by Japanese experts does not require complex catalysts, harsh conditions or long waiting times – the process takes no more than 10 seconds. At the same time, the traditional synthesis process of currently used nanobulbs is difficult and differs in the release of harmful substances into the atmosphere.
